How do I invoke another s/w from java code(urgent)

Question

Hi all,
My code looks like this :
Runtime rt =Runtime.getRuntime();
String command = "~/tts/bin/mbrola" +" ~/tts/mbrola/us2 " + " /home/dir1/dir2/final/temp.pho "+
" - | ~/tts/bin/mbrplay -";
rt.exec(command );
Whenever I ru n this code thru java , I get an error that this command was not found but am able to run it in my unix terminal. Would anyone have any clue as to why this is happening.
Thanks

SohiniHi,
I guess that you're trying to run command WITH arguments, aren't you?
So, you have to do it this way(just verify arguments):
    Runtime rt =Runtime.getRuntime();
    String command[] = {"~/tts/bin/mbrola", "la", "~/tts/mbrola/us2",
                                          "/home/dir1/dir2/final/temp.pho",  "-", " | ~/tts/bin/mbrplay", "-"}
    rt.exec(command);(making PROGRAM and ARGUMENTS an array - EACH argument SEPARATELY(I don't know their exact number in your script ))
Hope to help,
